Line Interface

Standard type Preferred standard compliance. Outcome is dependent upon standard support of the remote unit.

AnnexM This extends the capability of basic ADSL2 by doubling the number of upstream bits.

Line Type This specifies the type of channel on which the ATM VC’s cells have to be transmitted and received.

Possible choice: Interleave Only/Fast Only

* Interleave mode is used when transmission error correction is necessary due to a less than ideal telephone line.

* Fast mode will result in faster transmission rate.

Rate Mode This specifies what form of transmission rate adaptation is configured on this port.

fixed – Connect over the fixed speed given by ‘Tx Rate’ field, the connection gets fail if it can not reach the lengths and qualities of lines

adaptAtStartup – Connect over the range of speed given by ‘Tx Rate’ field, the connection gets retrain due to varying qualities of lines.

adaptAtRuntime – Connect over the range of speed given by ‘Tx Rate’ field, the connection is auto rearrange seamlessly due to varying qualities of lines.

SNR Margin (ATUC/ATUR)

Target SNR Margin This specifies Target SNR Margin which the ATU-R must achieve with a BER of 10 to the power -7 or better, to successfully complete initialization.

Valid values: 0 ~ 310 (dB/10)


Item Description

Maximum SNR Margin This specifies Maximum SNR Margin which the ATU-R receiver shall try to sustain. If the noise margin is above this level, the ATU-R shall request the ATU-C to reduce the transmit power to get a noise margin below this limit.


Minimum SNR Margin This specifies Minimum Noise Margin which the ATU-R receiver shall tolerate. If the noise margin falls below this level, the ATU-R shall request the ATU-C to increase the ATU-C transmit power. If an increase to ATU-C transmit power is not possible, a loss-of-margin (LOM) defect occurs, the ATU-R shall fail and attempt to reinitialize.


Tx Rate and Delay (ATUC/ATUR)

Minimum Tx Rate Configured Minimum Transmit rate for ADSL line channels, in bps.

Valid values (ATU-C Downstream): 32 ~ 28000 (kbps)

Valid values (ATU-R Upstream): 32 ~ 2784 (kbps)

Maximum Tx Rate Configured Minimum Transmit rate for ADSL line channels, in bps.

Valid values (ATU-C Downstream): 64 ~ 28000 (kbps)

Valid values (ATU-R Upstream): 0 ~ 2784 (kbps)

Maximum Interleave Delay Configured maximum Interleave Delay for this channel. Interleave delay applies only to the interleave channel and defines the mapping (relative spacing) between subsequent input bytes at the interleave input and their placement in the bit stream at the interleave output. Larger numbers provide greater separation between consecutive input bytes in the output bit stream, allowing for improved impulse noise immunity at the expense of payload latency.

Valid values: 0 ~ 255 (mSec)

Power Management

Power Management mode Power Management-related parameter used by ATU-C to set the allowed link states. Both bit values can be given simultaneously in the input.

L2 entry Rate (Kbps) Power Management configuration parameter. L2 state entry data rate.

Valid values: 0 ~ 30000

L2 Minimum Rate (Kbps) Power Management configuration parameter, related to the L2 low power state. This parameter specifies the minimum net data rate during the low power state (L2).

Valid values: 8 ~ 1024 (kbps)

L2 entry Time (sec) Power Management configuration parameter. Min L2 entry rate time

Power Management ModeThe power management allows you to furnish the efficiency of ADSL power output.

First-generation ADSL transceivers operate in full-power mode (L0) day and night, even when not in use. To address these concerns, the ADSL2 standard brings in two power management modes that help to reduce overall power consumption while maintaining ADSL’s “always-on” functionality for the user. These modes are the L2 and L3 power modes.

The L2 low-power mode enables statistical powers savings at the ADSL transceiver unit in the central office (ATU-C) by rapidly entering and exiting low power mode based on Internet traffic running over the ADSL connection. When large files are being downloaded, ADSL2 operates in full power mode (called “L0” power mode) in order to maximize the download speed. When Internet traffic decreases, such as when a user is reading a long text page, ADSL2 systems can transition into L2 low power mode, in which the data rate is significantly decreased and overall power consumption is reduced. While in L2, the ADSL2 system can instantly re-enter L0 and increase to the maximum data rate as soon the user initiates a file download. The L2 entry/exit mechanisms and resulting data rate adaptations are accomplished without any service interruption or even a single bit error, and as such, are not noticed by the user.

The L3 power modem on the other hand, enables overall power savings at both the ATU-C and the remote ADSL transceiver unit (ATU-R) by entering into sleep mode when the connection is not being used for extended periods of time. L3 is a sleep mode where traffic cannot be communicated over the ADSL connection when the user is not online. When the user returns to go on-line the ADSL transceivers require at least 2 to 3 seconds to re-initialize and to enter into steady-state communication mode.

Figure 4-6 Power Management Forced State


PvC SettingThe PVC Management dialog has the ability to configure the ATM PVC on ADSL port interface.

ATM (Asynchronous Transfer Mode) is more efficient than synchronous technologies like time-division multiplexing (TDM). With TDM, each station or users is pre-assigned some time slots, and no other station can send in that time slot. With ATM being asynchronous in nature, time slots are available on demand.

ATM supports integrated voice, data, and video communications. In ATM the information to be transmitted in divided into short 53 byte packets or cells, which have a 5 byte header. The reason for such a short cell length is that ATM must deliver real time service at low bit rates and thus it minimizes packetization delay. ATM networks are connection oriented with virtual channels and virtual paths. The virtual channel carries one connection while a virtual path may carry a group of virtual channels. This ensures that cell sequence is maintained throughout the network. The virtual channel is identified by the Virtual Channel Identifier, (VCI), and the virtual path is identified by the Virtual Path Identifier, (VPI). Both the VCI and VPI may change within the network and they are stored in the header of the cell.

AAL (ATM Adaptation Layer) makes the ATM layer services more adaptable to specific services. The specific services may include user services, control services and management services. The AAL is the layer above the ATM layer and it is responsible for converting the information from the higher layers into 48 byte lengths so that the ATM layer can add the 5 byte header to make the 53 byte cell. The two main functions of this AAL are to provide functions needed to support applications and to break up information into units that will fit into cells. There are five AAL layers and each layers is loosely associated with the class of traffic to be carried. AAL1 is designed to support constant bit rate, connection oriented, and synchronous traffic such as uncompressed video transmission. AAL2 is never completed, but it was envisioned to be assigned for variable bit rate, connection-oriented, synchronous traffic. AAL3/4 supports variable bit rate, connection oriented, and asynchronous traffic or connectionless packet data. AAL5 is the primary AAL for data and supports both connection oriented and connectionless data.

Valid values: 1 ~ 65535 (1 ~ 31 are reserved)

Type Be sure to use the encapsulation method required by the ATU-R. The NCT480 IP-DSLAM supports the following methods.

EOA: Ethernet over ATM. EoA benefits from SONET/SDH protection but has been criticized for being expensive and having scalability issues. EoA offers smooth roll out of Ethernet-based services in existing Asynchronous Transfer Mode ATM network and optimizes the use of spare capacity in the ATM network.

IPOA: Some CPE devices have IPoA interfaces towards the WAN side. These interfaces need to be supported and retained by the service providers. Also DSLAMs are moving from ATM to Packet mode and hence support for these interfaces on the CPE side becomes essential. In order to provide this flexibility in the route mode firmware release R2.0, RFC 2684 Routed (IPoA) interfaces along with the existing RFC 2684 Bridged Ethernet interfaces shall be supported.

PPPOA: PPPoA stands for Point to Point Protocol over ATM Adaptation Layer5 (AAL5). A PPPoA connection functions like a dial-up Internet connection. The NCT480 IP-DSLAM encapsulates the PPP session based on RFC1483 and sends it through an ATM PVC (Permanent Virtual Circuit) to the CPEs. Please refer to RFC2364 for more information on PPPoA. Refer to RFC1661 for more information on PPP.

Using all this information, an ARP request for the IP address specified in the gateway IP address of the default route. BRAS shall respond the ARP request from the NET side. Also due to source MAC address based learning, an entry in the MAC address-forwarding table will get created, which is required for the upstream forwarding. Hence, the upstream traffic can flow.

MAC (for IPOA) MAC address profile is a generic way for assigning MAC addresses to interfaces. A MAC address can be associated with a profile and that profile can be attached to the interface.

Currently a maximum of 48 profiles are supported in the system.

A VLAN allows a physical network to be divided into several logical networks. A device can belong to more than one VLAN group. Devices that are not in the same VLAN groups can not talk to each other. VLAN can provide isolation and security to users and increase performance by limiting broadcast domain. VLAN tag can be added to the MAC header to identify the VLAN membership of a frame across bridges. A tagged frame is four bytes longer than an untagged frame. Each port of NCT480 is capable of passing tagged or untagged frames.

Table 6-� Configuring VLAN Port Member


vLAN Mode SettingWith the Ethernet becoming cheaper and more popular, the Ethernet networks are expanding to cover metros. This is leading to deployment of MEN (Metropolitan Ethernet network). The existing support for VLAN as standardized in IEEE 802.1Q is not able to scale to MEN deployment, because of limited 4095 VLANs and hence the requirement for VLAN Stacking.

VLAN Stacking, also known as Q in Q, is the mechanism where one VLAN (Virtual Local Area Network) may be encapsulated within another VLAN. This allows a carrier to partition the network among several national ISPs, while allowing each ISP to still utilize VLANs to their full extent. It is very important to logically separate all traffic between ISPs – for security, for offering different levels of service to prospective ISP customers and the ability to utilize full VLAN space.

In a typical network scenario Columbia is on edge of provider network (Ethernet Aggregation Network), the location of DSLAM as shown in Figure 6-4 depicting Network Scenario.

Figure 6-4 Network Scenario


With VLAN stacking, if one ISP provisioned an end user into “VLAN 1”, and another ISP provisioned one of their end users into “VLAN 1”, the two end users would not receive each other’s traffic.

Figure 6-5 VLAN Mode Setting Dialog

Item Description

vLAN mode Single VLAN: The single VLAN Mode confirms to the normal 802.1Q VLAN support and the system will continue to work as is in the current model without VLAN stacking.

Double VLAN: VLAN used in VLAN aware networks based on 802.1Q bridging is called C-VLAN (Customer-VLAN), and can be uniquely identified by a C-VLAN tag VLAN that encapsulates Customer traffic in Provider network is called S-VLAN or Service VLAN and is identified by an S-VLAN ID, used as second VLAN tag. In this mode the features can be used to meet custom VLAN stacking requirements.


Table 6-3 VLAN Mode Setting Description


IGMP SnoopingThe IGMP Snooping allows you to view and change the IGMP Snooping administrate status.

IP traffic can be transmitted in one of either three ways: unicast (one sender to one receiver), broadcast (one sender to all members on the network) or multicast (one sender to a group of hosts). IGMP is a session-layer (layer-3) protocol used to establish membership in a multicast group.

Multicast addresses are Class D IP address, from 224.0.0.0 to 239.255.255.255. These addresses are also referred to as Group Destination Address (GDA). Each GDA address is associated with one MAC address. The GDA MAC address is constructed by joining 01:00:5E and the last 23 bits of the GDA multicast IP address in Hex. For example, GDA 224.1.1.1 corresponds to MAC address 01:00:5E:01:01:01

A layer-2 switch supported IGMP snooping can passively snoop on IGMP Query, Report and Leave packets transferred between Routers/Switches and hosts to learn the IP Multicast group membership. It snoops IGMP packets passing through it, picks out the group registration information, and configures multicasting accordingly.

Figure 6-6 IGMP Snooping Dialog

Item Description

DSLAM IGMP Snooping Status Specified whether or not IGMP Snooping is to be enabled in the system.

(ethernet) Port ID This specifies the network port interface.

vPI/vCI This specifies the virtual path, circuit identification for the PVC in the port.

IGMP Snooping Status A Bridge Port, for which IGMP Snooping needs to be enabled or disabled.

Leave Mode IGMP Snooping Leave message processing mode for the port.

If the mode is set to ‘Normal’, the Leave message is forwarded to the Querier and then based on the Query received from Querier the Leave processing is triggered.

If the mode is set to ‘Fast’, the port is immediately deleted from that multicast group on Leave message reception and then the Leave message is forwarded. The mode should be set to ‘Fast’ for a port only if there is one host behind the port. This is because if there are multiple hosts behind the port then it will lead to traffic disruption for other hosts who might still be listening to that multicast group.

If mode is set to ‘FastNormal’, the Leave message is forwarded and the Leave processing is triggered immediately without waiting for any trigger from the Querier. ‘FastNormal’ mode thus saves the delay (equal to the time taken for Leave message to reach router and Querier processing time for it and the time taken for Query to reach IGMP Snoop module) in Leave processing.

Table 6-4 IGMP Snooping Description


DhCP & PPPoe RelayThe DHCP Relay configuration provides DHCP Relay Option 82 function.

DHCP allows individual computers on an IP network to extract their configurations from DHCP server. The overall purpose of this is to reduce the work necessary to administer a large IP network. The most significant piece of information distributed in this manner is the IP address. Information can be added into client TCP/IP configuration requests that IP-DSLAM relays to a DHCP server. This helps provide authentication about the source of the request. Please refer to RFC 3046 for further details.

The PPPoE Relay feature enables an L2TP access concentrator (LAC) to relay active discovery and service selection functionality for PPP over Ethernet (PPPoE), over a Layer 2 Tunneling Protocol (L2TP) control channel, to an L2TP network server (LNS) or tunnel switch (multihop node). The relay functionality of this feature allows the LNS or tunnel switch to advertise the services it offers to the client, thereby providing end-to-end control of services between the LNS and a PPPoE client.

The PPPoE Relay feature enables an L2TP access concentrator (LAC) to relay active discovery and service selection functionality for PPP over Ethernet (PPPoE), over a Layer 2 Tunneling Protocol (L2TP) control channel, to an L2TP network server (LNS) or tunnel switch (multihop node). The relay functionality of this feature allows the LNS or tunnel switch to advertise the services it offers to the client, thereby providing end-to-end control of services between the LNS and a PPPoE client.


Spanning Tree ProtocolThe spanning tree protocol allows you to configure the STP parameters on network Ethernet interface.

Spanning-Tree Protocol is a link management protocol that provides path redundancy while preventing undesirable loops in the network. For an Ethernet network to function properly, only one active path can exist between two stations. Multiple active paths between stations cause loops in the network. If a loop exists in the network topology, the potential exists for duplication of messages. When loops occur, some switches see stations appear on both sides of the switch. This condition confuses the forwarding algorithm and allows duplicate frames to be forwarded.

To provide path redundancy to prevent undesirable loops, Spanning-Tree Protocol defines a tree that spans all switches in an extended network. Spanning-Tree Protocol forces certain redundant data paths into a standby (blocked) state. If one network segment in the Spanning-Tree Protocol becomes unreachable, or if Spanning-Tree Protocol costs change, the spanning-tree algorithm reconfigures the spanning-tree topology and reestablishes the link by activating the standby path.

STP is a technology that allows bridges to communicate with each other to discover physical loops in the network. The protocol then specifies an algorithm that bridges can use to create a loop-free logical topology. In other words, STP creates a tree structure of loop-free leaves and branches that spans the entire Layer 2 network.

ATM OAM TestThe ATM OAM test generates the ATM F5 loop-back to diagnose the ADSL port interface.

Operation Administration and Maintenance (OA&M) - OA&M is defined for supervision, testing, and performance monitoring. It uses loop-back for maintenance and ITU TS standard CMIP, with organization into 5 hierarchical levels: Virtual Channel (F5 - Between VC endpoints), Virtual Path (F4- between VP endpoints), and Transmission Path (F3- Between elements that perform assembling, disassembling of payload, header, or control), Digital Section (F2 Between section end-points, performs frame synchronization) and Regenerator Section (F1- Between regeneration sections).

Figure �-� ATM OAM Test Dialog

Table 7-2 describes the OAM test field items.

Item Description

Port(vpi/vci) Loop-back source id assigned to the ATM port. The ATM port will respond to all loop-back cells, which carry this OAM id. This parameter specifies the interface, virtual path, and virtual circuit for which information is desired.

Result Use this command to display result of previous OAM loopback command. This specifies the result of the loop back test. It may be Result Unavailable, Seg Succeeded, Seg Failed, E2e Succeeded, E2e Failed, Test Aborted, or Test In Progress.

ADSL2 DeLT TestDELT is primarily used for reactive tests on a loop after a CPE has been deployed, either to help troubleshoot a line or to capture a baseline of loop characteristics at the time of installation. DELT can determine the ADSL2+ data rate (up/down), loop attenuation (up/down), SNR (up/down), and noise (up/down).
